X. Foissac et al., SEQUENCE-ANALYSIS OF SPIROPLASMA-PHOENICEUM AND SPIROPLASMA-KUNKELII SPIRALIN GENES AND COMPARISON WITH OTHER SPIRALIN GENES, Current microbiology, 35(4), 1997, pp. 240-243
The spiralin genes from two phytopathogenic spiroplasmas, Spiroplasma
phoeniceum and Spiroplasma kunkelii, were amplified by PCR, cloned, an
d sequenced. Comparison of the amino acid sequences of the live spiral
ins analyzed to date confirm that the spiralins have a general amphiph
ilic character and possess a conserved lipoprotein signal peptide. It
also shows that a conserved central region and an amino acid repetitio
n, including a VTKXE consensus sequence, are present in all spiralins
analyzed.
